discussion: don't require filter pattern parameter to be quoted

[tstack]

I'm a bit biased, but I think it's a bit more user-friendly to not require the pattern parameter to be quoted. Having to escape regexes is pretty difficult. In the docs, there is this example:

:filter "\d{3} \d+"

However, I don't think it works as advertised. You have to add two backslashes for the \ds to actually work. Otherwise, the actual filter looks like this and doesn't match what is expected:

I agree that having to escape regex complicate things, and there were indeed issues with the current implementation.

I've reworked the filters, now there is a parameter for using regex filter --regex (or -r ), it no longer requires any of the filter to be escaped, the caveat is that now all parameters must come before the pattern.
